Trivia: All of the animals killed in this film were actually killed in real life. Because the film crew was in an isolated area, they did not have to contend with rules and regulations, and simply killed real animals rather than using props or effects. The director has since apologized, and has said he genuinely feels terrible about this fact.

Trivia: The director, and several other crew members were arrested after the film premiered, because authorities believed that the footage in the film was real, and that the actors were really dead. The director eventually had to present the actors to police to clear his name, and had to demonstrate how some of the gore effects (such as the impalement) were achieved.
